ed carpet. loomsfor the preparation and supply of tufting material of different colors .to one and the same tufting tool, whereby it is possible-to produce colored tufted carpets on the machine. i v

' The device is characterized by: movable guides or feeders in which endless pile threads of different colors are situated; Jacquard mechanism which controls the movable guides in any desired sequence; at least one gripping member intended to seize the pile threads and pull them out of the guides to the required length; a transfer device which is provided with take-, up members which "take these pile threads from the gripping member and supply them to the tufting tools or devices'of the carpet machine; a cutting device by which the pile threads situated in the take-up members, are cut to the length requiredrbefore they are supplied to the tufting tools of the machine.

The accompanying drawings illustrate by way of example a construction of the apparatus by means of which tufting thread of" siX different colors can be supplied to each tufting tool. g I Fig. 1v is a side elevation of the upper portion of a machine embodying my present invention.

15 is a sectional elevation of the guides 37. They are provided atone side with a pull lip 20 and at the otherside with a push lip 21. Their up and down movements are produced by a slide 22 which is operated ma correspondingmanner by an eccentric by means of alever 23 and a lifting rod2et. .The hooksare in a position of -rest normally as shown by dot and dash lines in Figure 6. )Vhen the card 2 has been advanced and has operated the cross wires 11, thesslide 22 will be moved downwards. Each pull hook 19 participates in this downward movement, partly by gravity and partly under the actionof a spring hereinafter described, until its push lip 21 strikes a "cross. wire that has been pushed back (Figures 3 and 6). The slide 22 descends to such an extentthat the pull hooks 19 can bring-back toinoperative position even the lowest cross wires 11. After each working pe1i0d,the slide22 returns again to the position of rest shown in dotted lines inFigure 6 and moves with it'to the position of rest all the pull books 19 whether set to a lower or higher position.

Above the pull hooks 19 is mounted a back slide 25 slotted like a comb, to span the :ess will be repeated.

pull hooks 19 whichcan thus be moved towards the back of-the crossvwires 11 and also away from the same (Figures 6 and 7). It is coupled by a link 27 to a lever. 28 which isconnected by means of the rod29 to-thetransport mechanism of the card 2* (Figure 1). As soon as the card 2' is moved towards the cross wires 11, the backslide- 25 is moved away from their'baclnso that the card'2 can push back the correct cross wires 11; The diameter-of each cross wired is greater than the width of the correspond ing slots in the slide 25 so that when the card 2 returns to the position of rest shown in Figure1,the.-back slide 25 will also be moved towards the cross wires 11' and will push-them back into the position of rest shown in Figure 7, so that all cross vwires 1 1 will be againrendered inoperative, and at the next advanceof the card 2, the proc From the bottom .end' of each pull hook 19, a flexible connection 30 (cord, wire cable or the like) leads to acatch lever'31 which is mounted so as to oscillate on a common spindle 32 Figures 1, 3, 9-12). The connection 30 leads over rollers 33 -which "are rotatably mounted on a supporting plate 34: (F igures2 and Thepitch.v

"ot the, catch levers 31 is independent in the lateral direction from the pitch of the pull hooks, as the connection 30 and the arrangement of the "rollers .33 allows it Each catch lever 31 is always'fpulled downwards "by atension spring 35, and in that way the connection 30 1is always heldquite taut. If

underthe' action of the card 2, the ,pull hook l 1 9 is' s'et to one or another cross wire 11 of .ures 1, 3, 9, 10, 11, 12 and 13).

a series, the corresponding catch lever 31 will'make a corresponding oscillation. The catch hook 36 mounted on thelother arm of the catchlever 31, is thus caused to oscillate to the right and returns to the original position as soon as the slide 22 returns the pull hook 19 to the position of rest.

.Ilnder each guide 37 is arranged the gripping member 5152 comprising a fixed gripping jaw 51 and the movable aw 52 (Fig- The movable'jaws 52 of the grippers are rigidly secured to one and the same spindle 53 which is rotatablymounted on'the fixed part 51.

which have reached the highest position in Figure .10. 'In this position the movable vjaw 52 closes and the thread 89 is thus gripped. The gripper 5152 descends then into the low position shown'in Figure 11,

carrying with it thethread 39 and pulling it through the guide 37. j

. On the left ofthegrippers 5152 are arranged levers 57 which belong to the transfer device and are secured to a spindle 59 rotatably mounted in eccentric levers 58 (Figures 1', 9, 10,11 and 12). The levers '57 are provided at the bottom end with a lug 60 (see also Figure 15) on which is mounted amoller "61; On thesaid roller acts an eccentric lever 62. Owingto the action of the eccentrics on the levers 62and 58, the

transfer levers-57, together with all the a parts mounted on themand described later,

are rocked in the direction of the arrow or in the opposite direction to an angle of about (single Figures 1 and 12). 7

At. the upper end of the transfer levers 5? are mounted, on a fixed connecting rail or bar 63, biturcated take oil members 64,

as well as on a movable'bar 65 bifurcated delivery members 66 (Figures 1, 12, 13, 15, '16, 17, 1S and 19). The' movable bar 65 lies flat on .the'connecting bar 63 and is held by covering guides 67. Onfth'e movable bar 65 is mounted a roller 68 wvhich @engages with a slot in a bell crank lever 69 mounted on a transfer lever ,On the same transfer lever 57 there is a second bell crank l'ever and the bell crank levers 69 and 0 are connected by a rod 71. 1 The bell crank lever '70 is again-'pivotedbymeans of a rod positions are shown in hialro also a radial nmvei irol.

of shears cuts at a time two threads; Figure 23 shows diagrammatically the position of the threads 39 before and after the advance of the shears.

-The severed thread 39 assumes thereafter the position shown in Figure 19, that is to say it is held fast in a double angle between the take off members 64 and the delivery members 66, and projects with the upper ends-beyond the take off members 64. These projecting ends are still in the way, and are ing-up,the ends of the threads (Figures 162O). On thesupport for the shears is arranged an angle bar 93 which is provided with stud like pusher-pins 94 bevelled downwards in front (Figures 9-13). Thepijtch of these pushers 94 harmonizes exactly with the slots 92. ranged,exactly'above the pushers 94, 'angu-' lar recesses 95 (Figures 21-23) into which the threads 39 are introduced at the'moment;

of cutting shown inFigure 11. The support then executes a further movement forward, from the position shown in Figure 11into the position shown in Figures 12, 13, owing to which the upper endsof the threads 39 are turnedover and pressed by the pushers 94 into the slots 92 and remain in that position (Figures 16"and 17) a-fterthe support 80 has again returned to the position of rest (Fig- In this way, the thread 39, completely ready for tufting or knotting, is situated in the take oif members arranged on the transfer levers 57; by swinging the levers 57, it is brought to the corresponding tufting tool (Figures 1 and 12). Each time, a pairof hooks 96 of this tool passes in the well known manner over a pair of warp threads 97 into the intermediate space of the takeoff member 64, rises a little, seizes on the return the thread 39 and pulls its ends over a pair of warp threads 97, whereupon tufting or knotting (Figure 14) takes place. It is obvious that the movable bar 65 opens slightly at the moment when'the hooks 96 lift the tufting thread 39 out of the take off members 64 and deliver thread 39 is released and comes out easily.

The support member 80 together with the shears 7 981 mounted on the same are horizontally movable in suitable guides 111 and are moved by means of 'eccentric levers 84 and a pivoted link or rod as indicated in Figs. 1, 25 and 26. This movement of the support member and the shears is towards and away from the verticalplane indicated, at MM The guides 111 slide on rods 112 (see Fig. 26) which by means of screw nuts 113 are secured to a support114. Thissupport 114 is secured by means of screws 115 On the angle bar 93 are ar-V members 66 so that the or otherwise to a part 116 of the machine frame. 'These members are illustrated in Fig.- 1 and more clearly shown in Fig. 25. The support member 80 is fixed by means of screws 117 to the guides 111. There are also guides 119 fixed by means of screws 118 to the shear supports 80. It will be noted that the movable shear support member 80 forms a sortof "bridge between the left and'right hand members of the machine, it being further noted that in Fig. 25 only the left handside member is'illustrated; The eccen tric lever 84 is connected with a lever .84 by means of a shaft 120 journaled in bearings 121. The lever 84 is provided wlth a roller 122 adapted to bear on the surface 'of-an eccentric 123, and'as will be understood, the rotation of this eccentric, through the mem: bers just described, causes'a horizontally reciprocating motion of the guides 111 and the parts connected thereto.

The working of the apparatus isas fol lows:

I The transport rollers 5 and 6 advance, whereby the card 2 pushes back givencross wires 11. The pull hooks 19 descend then as far asthe crosswires 11, so that the catch levers 31 are set in a corresponding manner. The guides 37 rotate and remain in engagement by means of the corresponding catch tooth 38, with the catch hook 36. Thus the colored threads 39 determined by the "card, are brought 'into the plane MM. The grippers 51'52 rise, seize the threads, 39 and pull them out downwards. The transfer latter.

The support 80 advances, whereby the threads 39 are brought between the shear blades7931 and cut by them at a suitable moment; 7 support 80, the upper ends of the threads 39 areturned over and fixed. The'transfer levers 57 then swing the threads thus prepared for tufting, within reach of the usual tufting tools which take them off and tuft them in the well known manner into the ground fabric of the carpet. All the parts return at a suitable moment to their position of rest or neutral position, whereupon the whole process is repeated. y g

In the construction described, it has been assumed that there are as many separate grippers 51-52 as there are feeders 37. But a common gripper could be provided, the jaws 51-52 of which are held in accordance with the length of the guides 37 arranged side by side; all the pile threads brought by the guides 37 into the vertical plane MM would'in these circumstances be seized by the common gripper.

The'tufting' thread maybe of wool or other material.
